sqrt - Maple Help

MTM

 sqrt
 compute square root
 realsqrt
 compute real square root

 Calling Sequence sqrt(M) sqrt(x) realsqrt(M) realsqrt(x)

Parameters

 M - array x - expression

Description

 • The sqrt(x) function computes the square root of x.
 • The sqrt(M) function computes the element-wise square root of M.  The result, R, is formed as R[i,j] = sqrt(M[i,j]).
 • The realsqrt(x) function is similar to sqrt(x) but requires that any numbers in the input be real and nonnegative.

Examples

 > $\mathrm{with}\left(\mathrm{MTM}\right):$
 > $M≔\mathrm{Matrix}\left(2,3,'\mathrm{fill}'=-3.6\right):$
 > $\mathrm{sqrt}\left(M\right)$
 $\left[\begin{array}{ccc}{1.897366596}{}{I}& {1.897366596}{}{I}& {1.897366596}{}{I}\\ {1.897366596}{}{I}& {1.897366596}{}{I}& {1.897366596}{}{I}\end{array}\right]$ (1)

Compatibility

 • The MTM[sqrt] and MTM[realsqrt] commands were updated in Maple 2021.
 • The 'realsqrt' option was introduced in Maple 2021.
